OIL-FEEDER.

SPECIFICATION forming part of Letters Patent No. 272,980, dated. February 27, 1883.

Application filed January 2, 1883.

a To all whom 2t may concern:

Beit known that I, DAVID SANDS ROBERTS, of Boston, in the county of Suffolk, of the Oommonwealth of Massachusetts, have invented a new and useful Improvement in Oil-Feeders; and I do hereby declare the same to be'described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a front elevation, and Fig. 2 a vertical and transverse section, of an oilfeeder containing my invention, the nature of which is defined in the claims hereinafter presented.

In such drawings, A denotes the body or oil-reservoir of the feeder, it being provided at its mouth with a cap or cover, B, screwed therein. From the central part of said cap an eduction-tube, O, extends upward, and at a short distance above the cap has out upon it a screw, a, upon which is screwed an auxiliary cap, D, which is open at its lower end, and thus, when screwed down, fits closely upon the top of the main cap or cover B. There is Within the chamber 1) of the auxiliary cap a vertical flange, c, that projects above the main cap B and surrounds the tube G concentrically. From the space within the said flange a tube, E, extends down within the oil-reservoir A nearly to its bottom, and there is fixed in the cap 1) another and shorter tube, F, that opens out of the top of the cap and terminates near the bottom of it and within the spaceinclosed by the flange c. There is also in the top of the cap D a cup or concavity, d, which surrounds the eduction-tube C.

From the above it will be seen that on inverting the oiler for the purpose of discharging oil from its tube 0 air will pass freely (No model.)

the pipeF, thence into the space within the flange c, and thence through the tube E and into the reservoir. The said flangcc operates as a fender or guard to prevent the escape of oil from the chamber b through the joint between the caps B and D. With my improved oil-feeder no oil can get on the outer side of the reservoir A, as any oil that may run down the outer surface of the educt C will be caused to pass back into the reservoir.

By having the chambered cap D separate from and screwed, as described, on the educt 0, ready access can be had at any time to the chamber 11, top of the cap B, and tube E, for cleaning either of any deposits therein.

I claim in the oil-feeder- 1. The combination of the auxiliary chamber b and its tube F with the reservoir A, its cover B, educt O, and tube E, all being arranged substantially as set forth.

2. The combination of the auxiliary chamber b and its tube F with the educt O, cover B, flange c, reservoir A, and tube E, all being arranged substantially as set forth.

3. The combination of the auxiliary cap D, open at bottom and provided with the tube F, and screwed upon the educt O, with such educt, the cover B, reservoir A, and tube E, arranged substantially as set forth.

4. The combination of the chambered cap D, provided with the cup d and tube F, as described, with the educt 0, cover B, reservoir A, and tube E, arranged essentially as repre- -sented.

DAVID SANDS ROBERTS.
